Yes, you can still use a userContent.css file. Place it in the /chrome
directory inside your profile directory. There should be a userContent-
example.css file in there with some examples and instructions.
You can still use a usercontent.css file, but the directory and example
files are not created by Firefox. So you need to create a directory
called "chrome" under your profile directory, and create a
userchrome.css file in it.
An alternative is to use the Stylish add-on which manages the additional
styles for you.

Here is a userContent-example.css which I found in the chrome subfolder
of my SeaMonkey profile. All examples are commented-out.

> /*
> * This file can be used to apply a style to all web pages you view
